Qrispy eSIM does not provide an unlimited data eSIM for Montenegro.
The vendor offers only pay‑as‑you‑go data credit, where a purchase gives the traveler a certain amount of data that can be used until the balance is depleted. The credited amount is a reference to the amount the balance buys at Montenegro’s local rates; it is not a hard limit, and the balance never expires, so unused data can be carried over to future trips.
Typical pay‑as‑you‑go options include plans that roughly ship 10 GB, 5 GB, 3 GB, 2 GB, and 1 GB of data at the current local rate. These credits are available for purchase without a fixed validity period, and the traveler can top up again whenever the balance runs low.
